Legacy Modernization Services in the UK

We perform a comprehensive evaluation of your application ecosystem to assess total cost of ownership (TCO), alignment with business capability models, and strategic modernization priorities.

• Enterprise application inventory. We establish a definitive repository of all enterprise applications, mapping business domain ownership, SLA profiles, and user base scale.
• Business value and criticality scoring. We evaluate workloads against strategic business criticality, operational risk, and run-rate expenditure to prioritize transformation investments.
• Technical debt & health evaluation. Framework age, architectural coupling, and maintainability are rigorously assessed to determine modernization feasibility and target state posture.
• Portfolio rationalization & consolidation. We identify functional redundancies, legacy overlaps, and candidate systems for decommissioning to streamline the portfolio prior to migration.
• Cross-functional executive alignment. We facilitate structured alignment sessions between business, technology, and finance stakeholders to ensure consensus on strategic priorities.

Infrastructure-level scans often miss complex code-level integrations. We conduct deep static and runtime code analysis to expose hidden architectural dependencies and prevent systemic cutover failures.

• Automated codebase analysis. Static code analysis and dynamic knowledge graphs expose hidden call graphs, shared database dependencies, and tight coupling missed by network scans.
• Systemic risk & artifact discovery. Hard-coded parameters, un-documented middleware configurations, and legacy environmental bindings are systematically mapped and remediated.
• Integration mapping. We document every connection between your applications and the external systems they rely on.
• Data flow analysis. We trace how data moves through end-to-end architecture, including where tight sequencing or shared state risks breaking a workload during separation.
• Cloud readiness report. You get a clear summary of what each application needs before it can move safely.

Using the established 6Rs framework, we evaluate each workload against operational requirements, cost drivers, and architectural complexity to select and document optimal transformation pathways.

• Rehost & Replatform strategies. Rapid transition options for stable enterprise applications requiring minimal architectural intervention while optimizing cloud infrastructure utilization.
• Application Refactoring & Modernization. Targeted architectural re-engineering to microservices or cloud-native paradigms for core differentiator applications demanding high scalability.
• Repurchase evaluation. We weigh keeping a custom application against replacing it with an off-the-shelf product.
• Retirement Decisions. Clear calls on what to keep on-prem and what to decommission entirely.
• Decision records. Every choice is documented together with its reasoning and trade-offs.

We engineer a rigorous financial model incorporating fully loaded TCO, migration capex, operational opex shifts, and business benefit realization suitable for executive board approval.

• Comprehensive TCO baseline. We quantify fully loaded existing expenditures, capturing infrastructure, enterprise software licensing, maintenance, facility overhead, and support operations.
• Cloud cost projection. We model right-sized cloud costs for each application and its chosen path.
• Licensing analysis. We show how your existing software licenses carry over to each cloud platform.
• Data transfer planning. We factor in the cost of moving data in and out of each platform.
• Phased budget. You get a spending plan that matches your migration waves, so costs arrive in manageable steps.

We architect robust, multi-cloud and hybrid cloud deployment models tailored to complex enterprise governance, security requirements, and workload specifications.

• Platform comparison. We evaluate each candidate against overall operational requirements and your team’s existing skills.
• Enterprise Landing Zone architecture. We design production-grade cloud foundations encompassing core networking, identity and access management (IAM), automated guardrails, and compliance baselines.
• Multi-Cloud Architecture. We plan how workloads can span environments when that serves you best.
• Portability by design. Containers and infrastructure as code keep future moves realistic.
• Security architecture. Identity and access controls are designed into the foundation from the start.

We translate strategic choices into phased migration waves and validate execution mechanics through controlled pilot migrations before full-scale deployment.

• Wave sequence planning. We group enterprise applications into structured migration waves optimized by dependency topologies, risk profiles, and business change windows.
• Pilot migration. We move a representative application first to validate both the plan and the tooling.
• Cutover Runbooks. Step-by-step guides are written for every switchover, including a tested way back.
• Team readiness. We help your engineers build the cloud skills they’ll need through pairing and hands-on sessions.
• Execution support. Our engineers can carry the plan through to completion or stand beside your own team as they lead it.

We conduct objective architecture reviews of existing or stalled migration programs to identify operational bottlenecks, optimize cloud expenditure, and restore execution momentum.

• Independent strategy review. We review your existing plan and share candid feedback on its risks and gaps.
• Stalled migration diagnosis. We find out why progress slowed, whether the cause is technical or organizational.
• Recovery plan. You get a practical path to restart, with clear priorities and realistic timelines.
• Cloud spend review. We audit cost drift and deliver concrete actions to bring spending back under budget.
• Hands-on recovery. Our engineers can step in and help get the work moving again.
